To all whom it may concern:

Be it known that I, LELAND B. WHIPPLE, a citizen of the'United States.residing at Rochester, in the county of Monroe and State of NewYork,have invented certain.

Improvements in Lasts, of which the following description, in connectionwith the accompanying drawings, is a specification,-

Lasts of this type are much. subject to criticism because of lack ofstrength 'an'd rigidity, and it is a principal object of the inventionto provide a last which will secure all the advantages of lasts of thistype w thout bein subject to thesedisadvantages,

invention resides in a. n'0vel organization of last parts having adividing cut comprising a re-entrant angle and a 'slmple and inexpensivelink-bonding me :hanism".-v

- 'This and other features of the invention, COIIlPl'lSlIlg variousarrangements and com-*- binations of parts will'be understood from thefollowin description which ,shows a referred em odiment or, theinvention, seec'ted for purposes o f'illustrationand shown and a contactface extending from said cor- ..ner=downward and substantially rearwardto the bottom of the last," and two non-par- 'allel links eachpivotedtin both last parts arranged one above the other,- the lower beinthe drawing in which,

Fig. l is a sectionviewof thelast in extended position; v v

Fi 2 is a'sectio'nal view showing the last in co lapsed positionayThe-last has a fo'repart'lO- and a heel part 12, divided'b a cut whichextends upwardly and forwar y, as-at 14;,to nearly the centerv .of thelast,-then' extendsforwardlyas at 16, and then upwardly as at 1-8 on theforeom an intermediate point of the segment -,to the top of thecone.

In te mbnyw art. The heel part .secant face 20 extends Thebondingmechanism "comprises fourrivets 22, 24, 26,28, the rivets 24, 26being located approximately-in-the same horizontal plane, while therivet 28 is considerably higher than the rivet- 122. These rivets arejolned by twolinks 29, 30,'as shown, the up per link 2? having a 111 32arranged to enga e ai-spring 34-, seate' 1n a hole 36..

. en the last-is extended, the side 37 of the re-entrant an le 38 restsupon the sur face 16 and aflfor a firm bearing against torsionalstresses, such as are imposed by the leveling machine. At the same time,the last 'is easily colla sibleby pressure and without the use; 0special tools or jacks.

The sloping cut14 permits the lower secant face onthe-heel part to passfreely over the corner-on the forepart formed by the cuts 14 and 16,without}. binding, as shown in dotted lines in Fig. 2. v v

The last described is simple in construction, not easily put out oforder, and-cheap to manufacture. It is at the sametime rigid Accoringly, a principal feature of the shoe-making and is easilycollapsible'when it v isdesired.to' .w'ithdrawthe shoe.

against the stresses met with in machine -,,-.1EIav ing fdescribed'myinvention, what I' claim-as new and desire to secure by LettersjPatent'of theiUnited States is A diyided last having a cut comprising are-entrant angl of approximately 90 in the 'he'el'part,.a corner on the;fore art, fitting into said angle-whenthe last. 1s extended,

part upwardly and forwardly past the saidreo corner on the forepart tocollapsed position. I ereof I' have signedjmy' name to thisspeclfication. I Y LELAND B. WHIPPLE.
